Description
The HR1001A is the OCP auto-recovery version of the HR1001B. The HR1001A is an enhanced LLC controller, and provides new features including adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP). Adaptive dead-time adjustment inserts a dead time between the two complimentary gate outputs automatically. This is ensured by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node. The ADTA features easier design, lower EMI, and higher efficiency.
The HR1001A incorporates anti-capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or has a severe overload. This feature protects the MOSFET during abnormal conditions, making the converter robust. The HR1001A has a programmable oscillator that sets both the maximum and minimum switching frequencies. It starts up at a programmed maximum switching frequency, and decays until the control loop takes over to prevent excessive inrush current. The HR1001A enters a controlled burst mode at light-load to minimize power consumption and tighten output regulation.
The device provides rich protection features, including two-level OCP, auto-recovery, external latch shutdown, brown-in/out, CMP, and OTP, improving converter design safety with minimal external components.
